Review of Cherry Resort, Temi in Sikkim, India

Written by Prithwiraj Bose on . Posted in Reviews of Products, Services and Websites

Temi is a small village of South-East Sikkim. Himalayan Ranges covered with green and thick rain-forest and varied colored flowers and birds makes this place a heaven on Earth. The wonderful Temi Tea garden adds to the beauty. Cherry Resort is located at the heart of Temi Hill, on the north west slide. Due to it’s geographic position, Cherry Resort is one of the best places in Sikkim to see mesmerizing Mount Kanchenjunga. In my review series this one is the Review of Cherry Resort located in Sikkim, India.

I have no choice other than writing this AliExpress Review. I am a frequent online buyer of cheap Electronic Components. And I buy regularly from Ebay and Banggood. I have been listening about AliExpress for a sometime now. And I thought of giving it a try. Suddenly something wrong happened with me and here I am writing this AliExpress Review about my worst experience!

LM317 High Current DC Regulated Power Supply Circuit

High Current DC Regulated Power Supply Circuit With LM317 – 5 Amp Current with Voltage Control

Written by Prithwiraj Bose on . Posted in Hobby Centre

Lets make a High Current power supply with LM317 Voltage Regulator which can supply upto 5 Amp. LM317 is one of the oldest, most used and wonderful linear voltage regulators. I personally love this IC (yes, it’s not a transistor) a lot, not because it server it purpose well, but because it’s cheap, easy and never disappoints you while making a regulated DC power supply. In this blog we will make a High Current power supply with LM317 Voltage Regulator and a couple of Power Transistors

Create an Obstacle Avoiding Arduino Robot

Creating an Obstacle avoiding Robot with Arduino, Adafruit Motor Shield v1 and Ultra-sonic Sensor

Written by Prithwiraj Bose on . Posted in Hobby Centre, Programming Tips Tricks Tutorials

Let’s make an Obstacle avoiding Robot. In this brief tutorial I will show how to build a perfect obstacle avoiding (run-away) robot using Arduino. I have used an Ultrasonic sensor mounted on a Servo Motor and a motor Shield for this project. The motor driver is Adafruit Motor Shield. This single shield is capable of controlling upto 4 DC motos and 1 servo motor simultaneously. Download link for the Arduino Robot Project Code (Arduino Sketch along with the required libraries) is available below. In this tutorial, I have not highlighted the instructions to setup the Robotic chassis along with BO Motors, Caster Wheel, Arduino Board etc. Rather I have concentrated on the how to extend the circuits to make it usable, connect the circuits and write the Arduino Sketch to make the Motors rotate by sensing the distance from Obstacles. When I created my first Arduino based Obstacle avoiding Robot, I was pretty much done with the mechanical connection, before getting stuck into the circuitry and programming. These were the 2 areas, where I struggled a lot and had to refer multiple tutorials to get a complete road-map. Here I will try to address those problems, which are often encountered by Newbies.
